Application filed July 18,1909. Serial No. 5117,339.

To all whom 'it may concern:

Illinois, haveinvented certain new and useful Improvements in Cars, of which the fol lowing is a specification. a 4

The object of my invention is to provide a car which may be used either as a box car or as a dump car.

- A particular feature of my improvements lies in an auxiliary floor comprising plates or pivoted members which may be made to lie either upon the floor of the car or in a vertical position against the side walls. \Vhen lying upon the floor they coverthe openings in said floor occupied by the usual drop doors. These auxiliary floor members prevent the loss of the contents of the car in case of the opening of the drop doors through accident, or through design on the part of thieves.

Another feature is to make those particular auxiliary floor members which are adjace'nt the side doors of the car serve as inside doors for the side door openings. These inside doors may serve as grain doors or may be used for any purpose in which a door or closure of less than full height of the door opening is desired, or in which a closely fitting door applied to said opening from the inside is desirable.

Another object of my improvements is to provide a floor of metal which will protect sill and underframe and which is thereby protected by the walls of the sill.

Other objects will be made apparent in the following specification and claims, taken in connection with the accompanying drawing, in which-- Figure 1 is a plan view showing principally the auxiliary floor members. Fig. 2

Fig. 3 is a crow section on the line 3, 3. Fig.4 is alongitudlnal section along the central line/l at one end. Fig. 5 is-a horizontal section with the v,

flooring removed on one side to show the underframe. Fig. 8 is a sectional plan viewon the central part of the car showing in a horih'e other in zontal position and position serving as an in's'ide door Fig. 7 1s a perspective view as seen from the in-v terio'r'of the car showing in detail the floor plates in an upright position. Fig. 8 is a ii vertical perspective view as seen from the interior of the car showing the floor plates lying in a horizontal position and showing the hinges by which the plates .are "attached to the floor and side walls. Fig. 9 is a perspective view-as seen from the interior of the car showingone of the floor plates in an upright position and serving as an inside door. Fig. 10' is an elevation of the hand lever and drop door mechanism at the end of'the car. Fig. 11 is a plan view of the same. Fig. 12 is a perspective view of a portion of one of the racks. 'Fig. 13 is a perspective view of the device for locking the hand lever in position.- Fig. 14: is a perspective view of the strip of iron which serves as a hinge member for, the inside doors Fig. 15 is a perspective view of another member of thleli hinge by which it is attached tothe side s1 In the drawings, the side walls 10, the roof 20 and the end walls 11 form the main body of the boxcar which is supported by the underframe comprising the center sills 13, side sills 21, and thetransverse sills 12.

The transverse sills 12 are fixed to the center sill 13 and carry thesidesills 21 at their.

,outer extremities. Hinged to the center sill 13 are the dump doors 1 1 which lie between the transvei'se sills 12 and close upwardly against an inwardly] projecting flange 21* of the side sills 21.

On the upper surface of the metal underframe are placed wooden floor pieces13 and 12. The dump doors 14 when closed are flush with the floor pieces 13 and 12.

The side sill 21 is an angle 'bar having one leg 21 horizbntally disposed and the other leg 21 vertically disposed and flush with the outer surface of the wall 10 of and when the 'VVhen-the said dump doors are not in use edges sufficiently t-he openings occurring at the hinged edges a of the dump'doors ered.

the car body. The narrow longitudinally disposed plates 22 are attached to wooden oor pieces 13 and project beyond their to serve as covers for there is always the possibility of their being accidentally or designedly opened, and then erably single steel f outer edges to the auxiliary floor members 16 and 17 very effectively prevent loss -.of the contents of the car.

' The auxiliary floor members 16 are prefplates pivoted to the side sills 21. Their dimensions are such as will permit them to reach from the side walls to the center of the car and'which will permit four. of them to be placed in the. end portion of the car between the end wall and the side doors.

The auxiliary floor members 16 are provided with elongated apertures or slots 30 by which they are loosely pivoted at their the hook bolts 31. These hook bolts 31 are given a right angular bend at 32 and a shank or body portion 33 is provided with'the shoulder 34 and the threaded portion 35 by which it is attached to the I horizontally disposed member 21 of the an- 35 gle bar 21. The nut 36 serves as a locking nut. The end 37 of the hook 31 is let into the socket in the side walls 10.

The metal plate 38 serves as a reinforcement for holding the said end 37 secure. The plate. 38 is held rigidly in place by two screws '39. The bend 32 is given an easy curve for permitting the slotted aperture 30 in the plates 16 to be easilg moved from the vertical part 33 to the hori: ital part 37 of the bolt.

Tue plate 16 is preferably given an offset to allow it to lie snugly on the'upper surface of the dump doors 14. This offset is of course equal to the thickness of the horizontally jdisposed leg 21 of the angle bar'21. The-plates 16 are held in an upright pos1- tion against the side walls by buttons or rotatable pieces 44, which are pivoted on the bolts 43 passing through the side walls 10. These clamps '42 have offset portions 44* which are designed to lap over the edge of the plate when'swung around to their holding position- The length of the vertical part. 33 of the bolt 31, as Well as the horizontal part 37 gives great freedom of movement to the plate. This'allows for the presence of small 4 fragments of coal, stone or other materials on the floor or in the corners without binding or without interference with the proper performance of the function ofthe auxiliary "the plates 16 for a The members 17 floor members 16. The elongated apertures 30 also allow considerable end movement of similar purpose.

The auxiliary floor members 17 which occur at the middle of the length of the car are constructed somewhat differently from the plates which have been described above. are designed to serve the combined purpose inside door. These floor members 17 when in an upright position lie across the lower portion of the side door openings 15 The location of these members is shown in Fig. 1 where they are seen lying upon the floor of the car. different from those of the Fig. 6 the central part of the car is shown on a much larger scale. In this'figure one of the floor members 17 is shown lying upon the floor of the car while the other is standof a floor member and an Their dimenslons are not greatly plates 16. In I ing in an upright position as it will appear when serving as an inside door. In Fig. 9 the details of the construction of the middle floor members 17 and their hinged and related parts are fully shown. At the middle of the length'of the side walls 10 are the door openings 15 commonly found in box cars. The door posts 15 comprise an outer main body of wood 15 and an interior metal portion 15. This inner piece .15 preferably consists of an ordinary channel bar in which ,the 7 15 is fixed. The door Wooden body portion posts as a whole space the outer door 15 from the side walls 10, and alsoserve the purpose of a door frame.

The door sill 15 comprises the wooden portion 15 and the metal plate 15 on the top surface thereof. The side door sill 15 complete is attached to the side sill 21 of the car frame. The hinged member 17 is provided with a body portion 50 made of Wood of considerable thickness and of a plate 51 which forms its upper surface when it lies in a horizontal position on the fioor of the car. Vhen in a vertical position and acting as an inside door the metal plate 51 is on the outer surface. The ends of the members 17 are beveled as shown at 52, and the wall is similarly beveled at 53 to permit the members to fit snugly within the door opening. The interior surface of the mem plate 51 to a distance suflicient to make a and outside doors 15 as bind the parts together.

The rivets 56 serve to The strip 54 is strong connection.

' I provided with a notch or'opening 57 to per- 'mit the insertion of a hinged member 58 shank 61 (see Fig. joins the flat portion 62 by whlch attachment is made to the angle bar 21 by means of the rivets or bolts in the holes 63. The stri 54, as well asthe wooden backing 50, is 0 set at 64'which permits it to lie snugly over the angle bar 21 and upon the floor of the car.

The members 17 are retained in their vertical position by hooks 70 which are pivoted on pins or bolts 71 fixed to the door posts The lower corners 72 of the members 17 are beveled to prevent interference with the beveled edges 53 of the wall boards and vto match the same and make a continuous floor surface when the members 17 are lowered. The door sill plate 15 is elevated a suflicient distance to bring its upper surface flush with thesurface of the members 17 when the latter are lowered. The filling piece 73 supports the edge of the plate 15 and prevents accumulation of material un 'der it.

The dump doors 14 are hinged to the center sill 13 by means of the hinge pins 18 .and brackets 80. The dump doors 14 are raised to their closed positions by the movement of the shaft 81, which in the present zontal portion 83 at their upper or outer ends.

The dump doors 14 are provided on their lower sides with the bars 84 which are bent to such form as will enable the shaft 81 to operate the doors in the desired. manner. The depression 85 in the bar 84 permits a wider range of opening of the door than would be effected if the bar 84 were straight. The inclined portion 86 culminating in the arallel portion 87 produces a quick closlng effect with a small rise of the shaft 81. The portion 87 lies in a horizontal position when the door is closed and the shaft 81 then has no tendency to slide from under it and permit the door to drop. In the same manner the horizontal portion 83 of the elongated opening 82 supports the shaft 81 without any tendency existing thereon to cause it to slide from its position.

At the end of the shaft 81 at the middle of the car the opening 82 in transverse sill 12 is omitted and the end of the shaft 81 can be supported at this point by the flanged supporting piece 88 which is riveted to said transverse sill 12.

The shaft 81 is provided with pinions 89 which mesh with toothed racks 90 fixed to the transverse sills 12. They are fixed in proper relation to the apertures 82 to permit meshing of the pinions 89 therewith,

while the shaft 81 travels along said apertures.

A portion of one of the racks is'shown.

in Fig. 12. v The body 91 of the rack is bolted to the web of the transverse sill. 92 are preferably of circular form projecting laterally from the body 91 and are strengthened by the ribs 93. In those transverse sills 12 of the car which perform the functions of bolsters and in which there are two webs 12, Figs. 4 and 5, the racks are attached to the inner faces of said webs. The rotation of the shafts 81 will cause them The teeth to move by virtue of the rack and pinion connection in a manner which will either close the dump doors or permit them to open, depending upon the direction of rotation.

The hand lever 100 is loosely or rotatably mounted upon the shaft 81 at a point outside the end walls of the car body. The hand lever is forked or divided into two flat portions 101, 102 at its pivotal connection with the shaft 81 and for approximat ly half the length of the lever. Between the divided parts 101 and 102 and fixed to the shaft 81 is the toothed wheel 103. The pawl 104 is pivoted to the lever by pin 105. The pawl 104: is placed between the divided parts 101 and 102 of the lever. The end 106 of the pawl is provided with oppositely disposed teeth for engagement with the toothed wheel 103 on either side of the lever 100. The lever 100 may by this means be made to rotate the shaft 81 in either direction. In the position ofthepawl 104 shown in Fig. 10, the shaft 81 would be rotated to the leftif the lever 100 were given an oscillatory movement. The oppositely disposed teeth 108 are so formed as to slip over the teeth of the wheel 103 when moved in one direction but to engage them when moved in the other direction. Adjacent said toothed wheel 103 on the shaft 81 is fixed another toothed wheel 107 which may be called a detent wheel. The detent 108 pivoted upon the floating member 109 at 110 is made to engage said wheel 107. The member 109 is preferably made of a steel plate pivoted upon the shaft 81 adjacent the wheel 107. This plate 109 is given a form somewhat similar to that of a lever, one end of which is pivoted to said shaft 81. The opposite end of the member 109 is provided with an elongated opening 111 which is adapted to encompass and slide upon a pin or stud 112 fixed upon the car body. The member 109 is thus ermitted 3 the interiorbf the car] and by this means its to accommodate its position to the movable shaft 81 as the latter moves outwardly and inwardly 1n the guide openings 82 in the transverse sills. While thus moving on the a shaft 81, it has a limited rotation or oscillatory motion about the shaft 8l,'but this movement is not of sutficient extent to pre vent itserving as'a support for aldetent ,108.

It is desirable'to lock the shaft 81 in its outermost position in which the dump doors 1 1 aregheld. closed. For this purpose a pawl 113: "ipi'voted u on the stud 112 outside of .the' 'lnember' 109 'utadjacent thereto, which isadepted to enga e a lug or projecting pin oil? Iart'114aupon the member 109. The pawl r ocln'ng'device 113 will drop by gravity l'aehn' d' saidlug 114 when the shaft 81 has neachedtits' outermost position. i The shoul- .',der. 115iwill bear against the lug 114 and prevent any movement ofthe member 109 tothe right. The finger 116 rests upon the top of the .lug li t and prevents the pawl from dropping below said lug.

1-, 'rhe hand lever 100 is held in its position of rest by a pin 117 carried by eyes 118 formed of the tongues 119' on the notched;

.' and formed plates 120. The notch 121 in said plate 120.15 adapted to receive the end of the lever 100. v I The pin 117 lying in the loops above the end of-the lever 100 vprevents the accidental raisingof said lever. The pin is attached to the angle piece 122 by the chain 123 to prevent its loss. when removed from the loops 118. The plate 120 is riveted to the angle] piece 122 and the latter is fixed to the upper surface of the end sill 124, The end sill 3124 is recessed at 125 for the accommodation ofthe hand lever 100 and associated mechanisrnl The slot 117 permits the, attachment of af'seal to prevent removal of-the pill 117 and the operation of. the dump doors.

'----'In"jorder to prevent entrance of water at the -base of the-side walls, the galvanized iron-flashing 130 is provided. vThe groove "131 in the lower edge of the lowest board of theside wall is used for the insertion of a rib or bead 132 formed in the-galvanized iron strip of which the said flashing is made.

vided, and the angle that is formed by said A downwardly projecting flange 1331s proflange with the main bo dy of the; flashing is made to lie upon-the corner of the angle bar 21. The water would have'to flow upwardly in ordertiopassover the .rib 132, .to reach entrance is effectively prevented. 4
